質問 # 203
An administrator set up a new user account called "test". However, the user is unable to change their password. Given the following output:
Which of the following is the most likely cause of this issue?
正解：D
解説：
For normal users to change their own password, /bin/passwd must have the SUID bit set (permissions should be -rwsr-xr-x). The SUID bit allows users to run the program with the permissions of the file owner (root), which is required to update /etc/shadow. The provided output shows /bin/passwd does not have the SUID bit (no 's' in the owner's execute field). As a result, user "test" receives an "Authentication token manipulation error". The password can be changed as root, which confirms it's a permissions/SUID issue.
Other options:
* B. If the password didn't meet requirements, a different error would appear.
* C. There is no minimum day limit preventing password change (see chage -l output).
* D. The account and password are active (not disabled).

質問 # 204
A Linux administrator needs to create and then connect to the app-01-imagecontainer. Which of the following commands accomplishes this task?
正解：A
解説：
The docker run -it command both creates a new container from the specified image and attaches to it interactively, which is exactly what the administrator needs.
質問 # 205
An administrator needs to append the output of a Linux command to an existing file for later analysis. Which of the following command-line strings should the administrator use?
正解：C
解説：
The correct answer is D. ls > > file.txt because the > > (double greater-than) operator is specifically used in Linux to append output to an existing file without overwriting its current contents. This is a fundamental concept in shell redirection and is widely used in scripting and automation tasks.
In this command, ls generates a list of directory contents, and > > file.txt ensures that this output is added to the end of the file. If the file does not exist, it will be created automatically. If it does exist, the existing content remains intact, and the new output is appended below it.
Option A (cat ls > file.txt) is incorrect because cat ls attempts to read a file named "ls," not execute the ls command. Additionally, > would overwrite the file instead of appending.
Option B (tee ls > awk file.txt) is invalid syntax and does not correctly use tee or redirection. The tee command is used to write output to both stdout and a file, but this example is malformed.
Option C (echo ls | sed -i file.txt) is incorrect because it does not execute the ls command; it simply echoes the string "ls" and attempts to modify a file using sed improperly.
From a Linux+ perspective, understanding redirection operators ( > , > > , |) is essential for automation and scripting. The > > operator is especially important when logging outputs, collecting command results, or building reports over time without losing previous data.
質問 # 206
A Linux administrator notices that an application is having trouble connecting to an external database. Which of the following commands should the administrator use to validate the connection to the remote port exposed by a database server?
正解：D
解説：
This command tests connectivity to a specific remote host and port, allowing the administrator to verify whether the database service port is reachable from the system.
質問 # 207
Which of the following describes how a user's public key is used during SSH authentication?
正解：A
解説：
During SSH public key authentication, the server checks if the user's public key is present in the
~/.ssh/authorized_keys file. If the key is found, the server uses it to verify the user's identity by sending a challenge that can only be answered by the corresponding private key. This process does not involve password hashing or using the public key directly for encryption of the communication stream. Instead, the public key is simply used as a reference for authentication.
